My Dog Has Diabetes: Now What – Cataracts?

Have you been asking the question – my dog has diabetes – now what? Unfortunately,  cataracts can be a horribly challenging problem for dog owners when starting insulin shots. I believe a reason the cataracts form so quickly has nothing to do with the insulin itself.  They can form overnight (or over a period of days or weeks) because inflammation runs rampant when you have not stabilized the insulin dosage. 

Studies Report Dog Diabetes Cataracts Can Be Reversed in 95% of Cases


Clinical Study Proves Can-C™ Safe and Effective for dogs

Thirty dogs (60 eyes) received topical application of Can-C 1% N-acetylcarnosine eye drop solution daily to cataracts.

Can-C Study Results

    • Visual acuity of subjects improved within weeks of treatment.
    • Cataracts shrank from the outside in.
    • Discoloration of the lens became more transparent.
    • Notable improvements were found in 96% of the eyes treated with Can-C™
    • Even dogs with long standing cataracts showed improvement in their sight.

CAN-C eye drops are a safe and natural alternative to cataract surgery. The research with dogs as subjects is undisputable: Vision improves and dog cataracts are reversed in most dogs.c_c100

CAN-C eye drops allow your dog’s eyes to heal themselves due to their anti-inflammatory nature. Inflammation creates an imbalance in the eye that accelerates conditions such as cataracts. By reducing the inflammation, CAN-C provides a foundation that the eye needs to heal naturally. Nature’s way is slower than surgery but it is far less invasive, less expensive and just as effective.

Cataract surgery of course is an option for your dog, but it involves considerable expense and some risk.   Of course, cataract surgery is not an option for many older dogs. Applying the CAN-C eye drops to your dog’s eyes does not involve the risk of surgical complications or side effects.

CAN-C drops improve the eyesight of dogs with cataracts because they restore the natural ability of the dog’s eyes to heal. Why? Free radicals are controlled with the application of N-acetylcarnosine, CAN-C’s active ingredient.

What Evidence Exists that CAN-C Drops are Effective for Reversing Dog Cataracts?

Remarkable improvements have been reported in the laboratory studies using dogs. The high potency form of N-acetylcarnosine that is found in CAN-C eye drops helps to reverse cataracts and improve visionRead Clinical Publication Abstracts of Dr. Mark Babizhayev, Ph.D.  from PubMed.            

Why Does CAN-C Succeed in Reversing Dog Cataracts?

What causes cataracts in the first place? Research reveals that the rampage of free radicals in the eye are the culprit. When oxidation is out of control, proteins that are naturally found in the lens of the eye are cross linked and connected as if they were glued together. Scientists call this a glycosylation process. The end result is a yellowing or browning of the pigmentation in the lens of the dog’s eyes. As the lens becomes more and more cloudy and as the discoloration becomes more pronounced, light that is able to reflect off of the retina at the back of the eye dims until no light is getting through, resulting in blindness.

This process is usually a gradual one. It can take a number of months before the dog begins to bump into furniture or is hesitant to play outside. Dogs treated with insulin will often experience a rapid deterioration in their sight.

If the oxidation process is left untreated, the dog’s sight will gradually deteriorate. One day your dog can jump up on a chair. The next day they cannot. One day your dog can fetch a ball. The next day they can not find the ball. Your dog eventually can not see anything.

There are many reasons that the oxidation process is triggered: exposure to ultraviolet light, toxins, pesticides, heavy metals and a wide variety of synthetic compounds, all of which contribute to an imbalance in the underlying conditions of the eye that are needed to keep it healthy.

Dr. Mark Babizhayev posed the question: how do the conditions differ in a dog with cataracts and a dog without them? He discovered a simple but very eloquent answer: dogs with cataracts were seriously deficient in one primary anti-oxidant used by the body to fight free radicals: N-Acetylcarnosine.

Dr. Babizhayev then posed the question: What if dogs with cataracts are given an eye drop that contains a high potency form of N-Acetylcarnosine? Will the inflammation be reduced?  Can formation of a cataract be slowed or even stopped?

His studies using dogs as subjects revealed startling results: Inflammation in the eye was reduced. Free radicals were reduced. The size of dog cataracts actually shrank. In 96% of the cases notable improvements were documented.

The prime ingredient in Can-C™ is a high potency form of N-acetylcarnosine that has been carefully formulated by Japanese scientists to provide a maximum anti-oxidant protection for the eye. Through experimentation, Dr. Babizhayev’s and his colleagues discovered that a potency which was too high or too low was actually not effective. Luckily, they were able to identify the correct molecular composition of N-Acetylcarnosine needed to facilitate the natural healing process.

Research Evidence on the N-Acetylcarnosine, Can-C™ Cataract Eye Drops for Dogs

The research program that led to the formulation of Can-C™ eye drops used today by thousands of dog owners was launched 11 years ago. Following the standard research protocol used to evaluate the effectiveness of all medicines and supplements, studies were first conducted in the lab using cell samples. After seeing promising results in the lab, the team of researchers launched the next phase of the research protocol: the evaluation of N-acetylcarnosine when applied to the eyes of dogs and rabbits with cataracts.

Studies of dogs yielded surprisingly positive results. Acuity of vision improved rapidly. Cataracts shrank. The protein linkages were disentangled. Cataracts became more transparent. As a natural anti-oxidant, no side effects were expected and none were observed in the studies. Beneficial effects of the treatment held.

The third phase of the research protocol used humans as subjects. Results were similar with one notable exception. Dr. Babizhayev found that the eyes of dogs are less defended than humans, so improvement in visual acuity was found to be quicker with canine subjects than when using humans as research subjects.

“The treatment of age-related cataracts in canines and rabbits has been conducted and the efficacy of using N-acetylcarnosine for cataract treatment was established. The striking results in canines and rabbits for both cataract reversal and prevention of lens opacities are clear.”

The special formulation of N-acetylcarnosine that was found in the studies to be effective is currently manufactured in Great Britain under the highest manufacturing standards. The Can-C™ eye drops are used today by thousands of dog owners today to effectively treat their dog’s cataracts.

The recommended dosage for dogs is one drop in each eye at three different times during the day. It is important to keep the eye saturated with N-acetylcarnosine throughout the day so that your dog’s eyes are protected from the damaging effects of oxidation and free radicals.

As a natural anti-oxidant, Can-C™ has not been approved by the FDA.   It is always a good idea to discuss with your veterinarian the use of any unapproved drug to treat your dog’s cataracts.


I purchased Can-C eye drops for my 10 yr old standard poodle Missy and have been applying the drops for a little over 3 months. Amazingly her eyes are now clear it has been a truly incredible experience to watch. She is more like her old self with renewed confidence and enthusiasm for life. Also our Vet was extremely impressed with Missy’s improvements. We cannot begin to thank you enough for this incredible product. – – DC – Jackson MO

Frequently Asked Questions about CAN-C Eye Drops

Question. My dog’s cataracts are a result of diabetes. Will Can-C help her?

It will probably take longer for you to see visible signs of improvement. Cataracts in diabetic dogs can be initially resistant to treatment. Owners tell us that improvements are generally found within two months after beginning treatment as long as the drops are consistently applied as directed. It is impossible to offer a precise estimate of the time required for the cataract to reverse because the effects of diabetes slows the healing process down as does the presence of mature cataracts that have ripened to the point of becoming more resistant to treatment.

It also helps to space out the times between when the drops are applied and the insulin is given. It is best not to give the insulin shot at the same time that you apply the Can-C™ eye drops.

Question: I have been told that my dog is too small for cataract surgery. Can I use the Can-C drops on her?

Yes indeed. Can-C has been used successfully on dogs of all shapes and sizes. The good news doesn’t actually stop here. Some people use the eye drops to treat their other pets including parrots, rabbits and hamsters. Rest assured that the Can-C eye drops are a safe and effective alternative to cataract surgery even though the size of your dog’s eyes is small.

Question: Do dogs with newer cataracts have a better success rate with this product?

If you begin applying the Can-C eye drops soon after noticing that a cataract has begun to form, you can generally expect quicker results. When a cataract has matured, it has likely already reached the stage of becoming somewhat hardened and calcified. As you can well imagine this makes it much more challenging for the dog’s body to reverse the cataract. When the cataract has reached an advanced stage – when it has thickened and calcified – it typically does take longer to achieve optimum results.

Question: Do your customers report a reversal in the size and density of their dog’s cataracts with use of Can-C eye drops?

Yes! We often receive phone calls and e mails from customers who report their dogs are happier and more active. They offer reports of positive shifts in the behavior of their dogs first. After 2-3 months of use, they can usually see the cataract begin to shrink. Customers who do not use the product as instructed will likely not experience optimum results. It takes dedication and a steady commitment to apply the drops every day to your dog’s eye, but persistence will pay handsomely.

The end result depends primarily on whether the eye drops are applied to cataracts that are ripe – meaning they have been growing and thickening for some time –  or if the Can-C eye drops are applied to eyes with cataracts that have just started to form. The outcome of course also depends on the consistency to which the eye drops are applied at three different times during the day. Recovery for dogs who have been injured or who are currently receiving insulin injections for diabetes also tends to be more challenging.

Most owners report improvements in the size and density of their dog’s cataract after 2-3 months of use. Optimal results are achieved within 6 – 12 months of use. Once the optimal level of improvement has been attained we always recommend that you apply only one drop a day to each of your dog’s eyes (instead of three drops). This mitigates against the possibility that the conditions which seeded the cataract in the first place are not re-created by excessive oxidation.

Question: What side effects can I expect from applying Can-C™ eye drops to my dog’s eyes?

None. The Can-C™ eye drops do not have any harmful interactions with any medicines your dog might currently be taking. There are no unwanted side effects. Application of Can-C eye drops does not induce any mineral or vitamin depletions in the body. Rather, the formulation of N-acetylcarnosine used in the manufacture of the Can-C™ eye drops provides your dog’s eyes with the natural anti-oxidant protection that is needed to restore integrity to the conditions necessary to support healthy eyes and good eyesight.

Can-C™ eye drops have been in widespread use for eight years throughout every country in the world without any reported side effects or complications. The soothing antioxidant properties of  Can-C™ eye drops make it possible for the dog’s body to heal itself without inducing any unwanted side effects.

Question. Are the Can-C eye drops approved by the FDA?

Lubricants used in the Can-C™ eye drops (Carboxymethylcellulose sodium) and (glycerin) have been approved by the FDA for ophthalmic use. However, Can-C™ is not approved by the FDA for the treatment of dog cataracts. N-Acetylcarnosine (1%) is listed as an ingredient that is inactive on the product labeling.

Question. What standards are involved in manufacturing the Can-C eye drops?

Can-C™ is manufactured in a GMP certified, pharmaceutical facility which meets ISO 9001:2000 and ISO 13485:2003 standards for the design/formulation and manufacture of sterile contact lens solution and pharmaceutical solutions. The eye drops are manufactured in a GMP (Good Manufacturing Procedures) facility according to strict protocols issued by Dr. Mark Babizhayev and government manufacturing guidelines.

Question. What are the chances that my dog’s eyesight can be restored if my dog has become blind as a result of a cataract?

In some cases dogs are able to better differentiate light and shadows better, but a restoration of sight after a dog has become blind is uncommon. Cataracts at this stage have ripened to the extent that they are significantly more resistant to the anti-inflammatory effects of Can-C™.   Reducing inflammation and free radicals in the eye is not necessarily sufficient to clear the calcification that has formed and reverse the process which caused the cataract in the first place.

Question. Is there any reason to even bother applying Can-C™ eye drops to my dog’s eyes if she is now blind?

Humans do not feel cataracts, but dogs feel cataracts as a constant irritant. That is why you may see your dog paw and scratch her eyes all the time. If you are a dog, having a cataract is like having sand caught in your eye which you can not rinse out. This irritation can be significantly relieved with use of Can-C™ eye drops.

A dog that is now blind is also a target for infection. It is sometimes necessary to actually remove a dog’s eyes in order to save her life. The application of Can-C™ eye drops reduces the chances of infection and the possibility the eye may have to be removed with surgery. It goes without saying that it is always advisable to follow the advice of your veterinarian in cases where the cataracts have become so problematic that your dog is now blind.

Question. To what extent are cataracts reversed with use of Can-C?

In many cases the cataract is fully reversed and vision restored. With a long lasting cataract that has “ripened”, there is usually some improvement in eye sight. Complete reversal of cataracts is not possible in all cases. It really depends on the maturity of the cataract. When the cataract has hardened and calcified, it is more difficult to restore vision. 

Dr. Babizhayev, as a veterinarian I want to let you know that I am now recommending N-acetylcarnosine (Can-C™) for the treatment of canine cataracts. After applying Can-C™ eye drops to the my 15 year old miniature pinscher, “Skeeter”, for one year, the cataract in his right eye has diminished! I have come to the conclusion that your cataract eye drops are a modern scientific miracle for our pets. From my observations it has prevented Skeeter from going blind and improved his overall aging experience! If your pet has cataracts ask your veterinarian or a pet ophthalmologist about this amazing product.

Question: How will I be able to tell if the product is working or not?

It is very difficult to tell if a human being has a cataract without an eye examination. Dog cataracts however are easy to see with the naked eye. You are encouraged to track the pace of shrinkage over time. What can you expect to see as the cataract is reversed?

It will shrink in size and become smaller. Your dog will likely experience an improvement in their peripheral vision before they are clearly able to see objects in front of them. Dog owners tell us that they observe a marked improvement in the behavior of their dog first. They become happier and more joyful as the irritating grind of the cataract is softened and their peripheral vision improves. They have much greater confidence to run and play as they used to do before sight became problematic because of cataracts.

The first sign they are working is a marked improvement in their behavior. The second sign they are working is a shrinkage in the size of the cataract. It is always a good idea to have your dog’s eyes checked regularly by a veterinarian so that you can track the improvement as it unfolds.

Question: Will my dogs cataract come back again after it has been reversed?

Yes. when the conditions in the eye that created the cataract in the first place are re-created in the dog’s eyes, it is very likely that another cataract will appear in one or both eyes. A new cataract can actually form relatively quickly since the underlying conditions that created the cataract in the first place are likely to still be present. Once the cataract has shrunk sufficiently and your dog has resumed his or her normal routine, we suggest that you reduce the dosage to one (1) drop in each eye daily. This will be sufficient to prevent the oxidation that created the conditions which caused the cataract originally.


Question: How long will each box of Can-C™ Eye Drops last?

Each box of Can-C contains two 5ml vials and each 5ml vial contains approximately 75 drops. When used to treat cataracts, one box of Can-C will last three to four weeks. Three (3) drops applied to each affected eye daily will last 25 days. When used as a preventive or maintenance measure only one drop in each eye daily is needed. When used to prevent the formation of new cataracts one box of Can-C will last 8 – 10 weeks.

Question: What are the ingredients?

Can-C Ingredients

Active ingredients: Glycerine (lubricant) 1%, Carboxymethylcellulose sodium (lubricant) 0.3%.
Inactive ingredients: Sterile Water (ophthalmic grade solution pH 6.7 to 6.9).
Antioxidants: N-Acetyl-Carnosine (NAC)* 1%.
Buffers: Borate, Potassium Bicarbonate.
Preservative: Purified Benzyl Alcohol.
Please read enclosed product insert for instructions on opening tubes. (*patented by Innovative Vision Products).

Question. Will the drops cause any discomfort or stinging in my dogs eyes?

Many dog owners tell us that their dogs beg for the drops because they feel so soothing and comforting to their eyes. The PH levels of Can-C has been formulated so that it has the optimal balance of alkaline and acidic properties.


Question. I have found another web site that sells N-acetylcarnosine eye drops. What is so great about your N-Acetylcarnosine eye drops?

It is actually not just the presence of N-Acetylcarnosine in the eye that makes reversal of cataracts possible. As it turns out, the molecular potency of the N-Acetylcarnosine used has to be of the highest quality. Dr. Babizhayev’s research revealed that only a particular potency was effective in shrinking cataracts.

This is the only formulation that has been shown in well controlled studies to shrink cataracts and safe for long term use. Other formulations of N-Acetylcarnosine sold in the marketplace have a wide range of potencies, none of which have been shown by research studies to reverse cataracts.
